Mitel MiVoice Business/MCD/3300 / Integrating Mitel, Lync and Exchange 2010 UM together
« on: September 28, 2011, 09:55:14 AM »
Hi,
Has anyone got all three of these working well together? The problem I am facing is that I can get our 3300 (4.1) integrated with Exchange using SIP - the VM functions all work and MWI works.
I can get the 3300 integrated with Lync via a different Sip trunk with calls passing between them just fine
Lync and UM also works fine
The problem is if I try to configure everything so calls to both mitel and Lync users go to exchange using just a single trunk to lync.
ie: mitel->lync->Exchange um
in this configuration I can dial the exchange um SA number from a mitel handset - exchange answers and recognises the extension I am calling from and prompts me to log in. However when I set up the call re-routing on the mitel system to re-route calls to the same SA number if an extension is busy or unavailable the exchange server answers with a generic prompt asking for my mailbox number rather than with the user's greeting and prompting for a message.
On the mitel side I have a system speed call that dials the SA number which is routed via the lync sip trunk.
Hope that makes sense? any help would be appreciated - or is what I am doing impossible and I have to just go with two sip trunks - one to exchange for UM for mitel extensions and one to lync for lync extensions?
Cheers,
Sam
